Seed treatments can cause a deterioration in seed singling, spacing accuracy, and seed flow into the vacuum seed meter. To minimize the effect seed treatments may have on vacuum meter performance, John Deere Talc Lubricant should be used whenever treated seed is being planted.
Some commercially-applied seed treatments or farmer-applied seed treatments may cause a deterioration in seed singling, spacing accuracy, and seed flow into the vacuum seed meter. To minimize these adverse effects, John Deere Talc Lubricant should be used whenever treated seed is being used.
If planting commercially-treated seed and no farmer-applied treatments are being used:
Spread 1/2 cup of talc over the top of each hopper full of seeds after filling the hopper. Adjust this rate as necessary so all seeds become coated with talc, while avoiding an accumulation of talc in the bottom of the hopper.
For small seed sizes, seeds with heavy treatment, or for humid planting conditions, increasing the rate to one cup per hopper full of seed and mixing thoroughly may be required.
If adding a farmer-applied treatment to the seed:
Fill the seed hopper 3/4 full with seed and apply the recommended amount of seed treatment to the seed.
Following manufacturers recommendations, thoroughly mix the treatment into the seed to get uniform coverage of treatment on the seed.
Apply 1/2 cup of talc to the seed and mix thoroughly again. Adjust this rate as recommended above for small seeds, seed with heavy treatment, or for humid planting conditions.
IMPORTANT:
Be sure to apply the seed treatment to the seed BEFORE applying talc

lubricant to insure that the treatment adheres to the seed properly while minimizing buildup on meter components. If buildup of treatment still occurs, contact your chemical manufacturer for assistance.
Replace hopper lids after hoppers have been filled. If lids are left off, dust and dirt can accumulate in the seed metering mechanism, causing excessive wear.
NOTE:
Using liquid hopper applied seed treatments which leave a wet coating on the seed is not recommended.
IMPORTANT:
If farmer-applied treatments are used, be sure to follow the chemical manufacturer's recommendations carefully. Dry powder or fast drying liquid treatments are generally recommended. HIGH OIL CONTENT TREATMENTS ARE NOT RECOMMENDED.
Chemical reaction between farmer-applied seed treatments and treatments commercially applied to seed can cause the seed treatments to become sticky. Certain temperature and humidity levels can further complicate material compatibility. Treatments that adhere to the vacuum meter components can cause reduced population and spacing control.
Check with your chemical and seed supplier for treatment compatibility.
